DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

In one embodiment, at least one of the methods, devices, computer systems, or computer program products disclosed herein is utilized for automated data collection (ADC) from a subject in a healthcare setting. In one embodiment, the methods, devices, computer program products, or computer systems disclosed herein assist in ranking the criticality of a subject in a healthcare (e.g., critical care or emergency room) setting and using the criticality of the subject to assign a Queue Status Indicator (QSI), which indicates the priority sequence for subjects in the queue awaiting medical attention. In one embodiment, the queue of subjects is updated in real time with one or more of temporal, spatial, or subject-specific data. In one embodiment, the methods, devices, computer systems, or computer program products save healthcare settings time, money, and reduce errors by increasing efficiency and collecting and presenting accurate information about each subject in the queue. Likewise, the methods, devices, computer systems, or computer program products provide benefits to subjects, including but not limited to, customized attention, higher priority ranking when warranted, and faster treatment. Thus, various embodiments disclosed herein assist healthcare facilities, particularly emergency departments, address quality of service and safety concerns. Further, the high level of data collection from the subject at the beginning results in fewer re-billing events for payment of services due to inaccurate information received, or mistakes made on intake of the subject to the healthcare facility.

In one embodiment, the methods, devices, computer systems, or computer program products also access any electronic health records that can include, among other things, the subject's past medical problems and/or treatments as well as possible identifying information.

In one embodiment, the subject includes a human. In one embodiment, the subject includes a healthcare worker. In one embodiment, the computer systems, devices, methods, computer program products determine whether a healthcare worker is well enough to go to work, enter a particular healthcare area, or perform a certain task. In one embodiment, the subject includes a healthcare patient. In one embodiment, the subject is a fetus. In one embodiment, the subject is a non-human animal. In one embodiment, the subject is a mammal, amphibian, fish, bird, or reptile. In one embodiment, the subject is a baby or child. In one embodiment subject is a geriatric. In one embodiment, the subject is a non-adult. In one embodiment, the subject is a cow, horse, dog, cat, or other domesticated animal.

In one embodiment, the systems, devices, methods, and computer program products described herein do not diagnose a subject. In one embodiment, the systems, devices, methods and computer program products described herein do not treat a subject, but rather assess the criticality of the subject. In one embodiment, the systems, devices, methods, and computer program products described herein rank the subject in sequential order when compared with other subjects in the queue, depending on the criticality of the subject's condition, as measured by an assessment, including among other things, one or more data collection questions (DCQs).

In one embodiment, a particular subject undergoes assessment with one or more sensors. For example, in one embodiment, the subject is assessed with one or more first sensors that then activates one or more second sensors, depending on the conditions sensed and criticality of the subject based on the first sensing (and optionally, consideration of information included in a subject's health record(s)) a first sensor initiates a system (e.g., a subject passes by it or enters the facility), or self-reporting of characteristics (e.g., symptoms) by the subject. In one embodiment, the subject undergoes assessment based on a decision tree originating with the first sensor and/or self-reporting of characteristics (e.g., symptoms) by the subject. (See for example, Shi et al., Science Direct pp. 2016-2028, Vol. 42 (2007); U.S. Patent App. Pub. No. 2010/0049095, the content of each is incorporated herein by reference.) For example, nonphysiologic and physiologic sensing can be performed by one or more sensors of the system alone or in conjunction with biological assays, which can be performed by the system (blood glucose finger prick test, breathalyzer, DNA swab, etc.), or self-reporting by the subject of any characteristics (e.g., symptoms) and of the subject's perceived severity or criticality of such characteristics (e.g., symptoms) (e.g., battery of questions or a figure of a human or other model subject for reporting the location of pain or other trouble) in order to generate one or more Characteristic Values for the subject. In an embodiment, the subject is unaware of the assessment with one or more sensors. In an embodiment, the subject is unresponsive or unconscious. In an embodiment, the subject is given a choice as to whether to be assessed by the one or more sensors.

Next, depending on the results of the assessment (i.e., sensed conditions, biological assays, self-reported characteristics, and optionally the subject's health record(s) (e.g., electronic health record)), and the corresponding Characteristic Values for the subject, based on comparison with a characterization value dataset. Once the Characteristic Values for the subject are generated, the subject is assigned a Criticality Value based on comparison with the criticality value dataset. In one embodiment, sensed, assayed, or reported characteristics are compared with known values, including but not limited to a database of standardized values, or a subject's own health history values. Based on the Criticality Value of the subject, a decision is made utilizing instructions implemented on a computing device (network, etc.) to initiate a second set of sensors, biological assays, or data collection questions (DCQs). The second assessment can be predetermined or customized for a particular subject, depending on the needs of the healthcare facility or the needs of the subject.

In an embodiment, the subject's Criticality Value is compared with the Criticality Value dataset including the Criticality Values previously generated for subjects in the queue. In one embodiment, the subject's present Criticality Value is compared with the Criticality Value dataset including Criticality Values previously generated for the subject based on his or her own health history.

For example, if it is detected or self-reported that a subject has a fever and elevated heart rate, the information from the subject's health record (or information from friends/relatives that are with the subject) can be considered in order to determine which immunizations the subject has or has not received. This may prompt a DCQ of asking the subject if he/she has traveled anywhere recently, or been in close proximity to someone who has. This may also illicit further sensors to sense additional characteristics or the system to perform biological assays (e.g., finger prick for blood test with PCR for pathogens, etc.) and evaluate the overall condition of the subject based on the sensed conditions. If further sensors or biological assays indicate that the subject has no other symptoms, for example, this finding will reduce the overall Criticality Value of the subject and will assign a Queue Status Indicator accordingly.

In one embodiment, at least one first sensor or other components of the system is in operable communication with at least one second sensor or other component. In an embodiment, the at least one first sensor or other component is in wireless communication with at least one second sensor or other component. Various modes of wireless communication are described herein. In one embodiment, information obtained or collected regarding the subject is shared or transferred from one part of the system to another. For example, the results of an assay can be entered into the subject's medical records, or the subject's health records can direct the focus of a sensor for assessing the subject's present state of health. In this way, in an embodiment, the system represents an integrated system of multi-directional communication between a subject, a healthcare worker, one or more databases, and one or more assays, sensors, or self-reporting queries.

In one embodiment, at the time the subject first enters the healthcare facility, he or she can refuse to have any data collected by way of assessment (e.g., sensors, biological assays, health record (including prescription records, stored electronic monitoring data, etc.), family health history (including questioning family members), or DCQs). In such a situation, for example, the subject may still provide a fingerprint, driver's license, social security number, birth date, anonymous unique identifier, or other form of identification for check-in, and optional accessing of the subject's health records. In one embodiment, a date and/or time stamp is registered at the time the subject checks in or begins the assessment process. In one embodiment, if two subjects would otherwise be assigned the same QSI, the date or time stamp that is earlier in time will trump the later in time subject. In this way, two subjects with the same level of criticality will be seen in the order in which they arrived at the healthcare facility.

In one embodiment, the systems, devices, methods, or computer program products described herein include the ability to interact with additional information from, for example, another computer system of dataset (e.g., personal data storage, personal monitoring device or sensor network, patient tracking system (e.g., Amerlior EDTracker), information system (e.g., Amelior ED), network sensors (e.g., mT Tag™ or other network sensor), implanted sensors, or user input. See for example, U.S. Patent App. Pub. Nos. 2007/0088713, and 2006/0212085, each of which is incorporated herein by reference.

In one embodiment, the systems, devices, methods, or computer program products described herein include access to the subject's health history (e.g., individual and/or family health history). In one embodiment, the systems, devices, methods, or computer program products use artificial intelligence for at least one step of the described embodiment(s) (e.g., OSCAR-MDA, CodeBlue, etc.).

In one embodiment, the systems, devices, methods, or computer program products described herein include interaction or tracking information with other datasets, for example, a public health database (e.g., CDC, NIH, state or local agency database, etc.). In one embodiment, the systems, devices, methods, or computer program products described herein access and interact with infectious disease information, bio-weapon or chemical weapon information (e.g., Homeland Security), adverse effects of drugs or equipment (e.g., for manufacture recalls), or healthcare facility statistics (e.g., infection rates, hygiene, liability, etc.). In one embodiment, a decision may be made based at least partly on information received from such a database, that the subject must be quarantined. In one embodiment, information is transferred one or more directions, including updating databases with infectious disease or other public health issues (signs of bio/chemical weapons), adverse effects to drugs or equipment (e.g., for recalls), hospital issues such as infection rates, hygiene, or liability.

In one embodiment, the Criticality Value of the subject, or one or more Characteristic Values, satisfies a threshold condition, and optionally indicates that one or more Characteristic Values of the subject must be monitored. For example, the subject can be monitored continuously or intermittently (e.g., at predetermined times or customized times) based on the subject or subject's condition.

In one embodiment, one or more sensors utilized in assessing the subject, including one or more remote non-conductive sensors, are located in one or more of furniture, wall, floor, door, doorway, reception counter, pen, computer monitor or other hardware, or computing device from which a subject is self-reporting one or more characteristics (e.g., symptoms). In one embodiment, the one or more sensors are included in an exam table, chair armrest, gurney, or other furniture.

In one embodiment, the one or more sensors include at least one of ultrasound, bioimpedance, or infrared thermometry. In one embodiment, the one or more sensors include audio sensors (e.g., cameras that are audio and/or video recorders), or eye tracking (e.g., imagers). See, for example, U.S. Patent App. Pub. Nos. 2010/0049095; 2006/0190419; 2008/0039698; or 2010/0174533, or U.S. Pat. No. 6,475,161, each of which has been incorporated herein by reference.

In one embodiment, one or more subject specific characteristics are measured, including but not limited to characteristics of the subject including at least one of height, weight, fingerprint, facial features, visible physical malformations, eye characteristic, appearance of skin, appearance of hair, appearance of nails, respiratory sounds, body temperature, blood gas level, heart rate, brain electrical activity, respiration rate, facial expression, blood chemistries, blood cell counts, platelet counts, antibody titer, calcium level, blood antigen type, tissue antigen type, evidence of a pathogen exposure, lipids levels, perception of pain level, body movement, gait, stiffness, evidence of cognition state, dehydration, self-reported pain, self-reported malaise, self-reported injury, self-reported event, rigor, fever, self-reported light-headedness or dizziness, self-reported dry mouth, self-reported nausea, self-reported shortness of breath, self-reported thirst, weakness, self-reported sleepiness, hearing loss or problem, vision loss or problem, self-reported constipation or diarrhea, flatulence, self-reported urinary incontinence, self-reported loss of smell or problem, self-reported loss of voice or problem, self-reported loss of taste, self-reported loss of ability to walk, self-reported loss of ability to write, self-reported loss of ability of limb or digit use, or other characteristic. For example, the appearance of skin, hair, or nails can be evaluated by standard criteria, including but not limited to hair loss or change in condition, change in any birthmarks, tattoos or skin blemishes (or arise of any new birthmarks, moles, or other skin marks), body odor, change in nail condition, damage due to exposure to sun or chemicals, etc.

In one embodiment, one or more subject specific characteristics are assessed by one or more direct or indirect sensors (e.g., remote non-conductive sensors). In one embodiment, one or more subject specific characteristics are assessed by self-reporting by the subject. For example, in one embodiment, the subject interacts with at least one input/output computing device (e.g., kiosk, tablet, desktop, laptop, handheld device, etc.) and responds to data collection questions (DCQs) relating to his or her characteristics (e.g., symptoms). For example, in one embodiment, the subject may be presented with (in any number of different possible languages) DCQs relating to one or more characteristics of: abdominal pain, knee pain, blood in stool, low back pain, chest pain, nasal congestion, constipation, nausea or vomiting, cough, neck pain, diarrhea, numbness or tingling in hands or feet, difficulty swallowing, pelvic pain (female or male), dizziness, eye discomfort and/or redness, shortness of breath, foot or ankle pain, shoulder pain, foot or leg swelling, sore throat, headache, urinary problems, vision problems, heart palpitations, hip pain, wheezing, joint or muscle pain, skin rash or other rash, earache, or other symptoms.

In one embodiment, the DCQs asked of the subject are directed based on previous answers provided or other information known about the subject (e.g., by way of the self-reporting, or by way of electronic health record, sensed information, etc.). For example, the DCQs may be different based on the person's gender, health history, or response to answering a first round of specific DCQs. In one embodiment, the DCQs are prioritized, for example, with the first DCQ has a heavy weight assigned due to its criticality, and depending on the response to the DCQ, the DCQs that follow are tailored to address the concerns presented in the prior response.

For example, if a subject with a history of heart disease enters the healthcare facility, and a first remote non-conductive sensor senses and signals that the subject has an irregular heartbeat, a second sensor quickly determines if the subject is responsive enough to answer DCQs. If so, one of the first DCQs for this subject could be: “Do you have chest pain?” If the subject responds, “Yes,” then a second DCQ could be, for example: “Rank your level of pain on a scale of 1 to 5, with 5 being greatest level of pain.” Again, depending on the response, with each DCQ receiving a particular numerical Characteristic Value, the DCQs will be adjusted specifically for the reporting subject. For example, if the subject reports a high level of pain “5,” the system will determine that the subject has a high Characteristic Value, and when compared with the Characteristic Value dataset, generates a Criticality Value, which in turn is assigned a high Queue Status Indicator (QSI). The subject's QSI is determined by comparing the subject's Criticality Value with the Criticality Value dataset, including Criticality Values from subjects in the queue, if any, or Criticality Values from this particular subject, based on his or her own health history. When one or more Characteristic Values or Criticality Value(s) satisfy a threshold condition, the subject is awarded a higher QSI, potentially moving him to be first in line to receive medical attention. In the event that the subject's one or more Characteristic Values or Criticality Value(s) satisfy a threshold condition, the subject may receive an alert that indicates he or she will continue to be monitored (e.g., by one or more sensors, DCQs, or other means), and is continually assessed for changes. If the subject's health condition is both critical and unstable, for example, a location indicator is immediately activated in order to identify the location of the subject within the healthcare facility.

However, in the same example, if the subject responds, “No,” to the first DCQ of “Do you have chest pain?” Then a second DCQ could be: “Do you feel dizzy or lightheaded?” If the subject responds, “No,” the subject's responses are assigned a lower Criticality Value than in the first scenario. However, the subject may still receive a high QSI based on his history of heart disease and presentation of heart palpitations. In this case, the subject would still continue to be monitored by one or more sensors for any change in condition, which could result in a change in QSI based on the Criticality Value of any changed assessment measurements.

In one embodiment, the information input from the subject is assigned varying degrees of confidence depending on the source of the information, in order to reduce conflicting information. For example, if a subject self-reports a high level of pain, but sensors detect no corresponding characteristics typical of a high level of pain (e.g., rapid heart rate, perspiration, agitation, facial expressions of discomfort, etc.), the self-reported Characteristic Value of a high level of pain may receive a lower numerical value than if the one or more sensors verify characteristics typical of a subject's being in a high level of pain.

In one embodiment, exemplary DCQs include but are not limited to, “Do you smoke?”; “Do you have any allergies?”; “Do you have any changes in skin or hair?”; “Do you have shaking or tremors?”; “Do you have numbness anywhere in your body?”: “Have you traveled lately?”; “Do you have difficulty swallowing?”; “Have you ever had a fainting spell or convulsion?”; “Do you have any lumps or bumps in your body?”; “Please indicate whether you are male or female.”; “Are you pregnant?”; “Any change in appetite?”; “Are you sexually active?”; “Do you have any vomiting?”; “Do you drink alcohol?”; “List any drugs ingested in the past 24 hours, including recreational or pharmaceutical drugs.”; “Have you had any medical biological assays or treatments (including surgeries) lately?”; “Rate your pain on a scale of 1 to 5, with 5 being the highest amount of pain you have ever had.”; “How is your energy level?”; “Are you socially withdrawn?”; “Have you been feeling anxious lately?”; etc. Further examples of potential questions are available, for example, in U.S. Pat. App. Pub. No. 2004/0138924, which is incorporated herein by reference.

In one embodiment, if two or more subjects would be assigned the same QSI based on each of their Criticality Values, respectively, then a date/time stamp from the initial check-in of the subject at the healthcare facility will determine which subject receives a higher priority QSI, with the subject presenting earlier in time receiving the higher QSI. In one embodiment, as described elsewhere herein, if one or more Characteristic Values of a subject changes, the system will update the dataset and the subject's QSI may change, depending on the QSI and condition of the other subjects in each dataset. Thus, in one embodiment, the dataset is dynamic (Characteristic Value dataset, Criticality Value dataset, Queue Status Indicator dataset) in that it is updated when new data is collected for a new subject entering the queue, and/or it is updated when the status changes of a subject already in the queue. In one embodiment, the corresponding dataset will update based on the subject's changed status, which will in turn update each dataset accordingly. For example, if one or more Characteristic Values of a subject are being monitored and one or more change, then the subject's Criticality Value will change accordingly. When compared with the Criticality Value dataset, the subject's Queue Status Indicator will change to correspond with the change in the subject's Criticality Value.

As another example, a subject enters the waiting room, activating a sensor (subject can be responsive or unresponsive). The subject is immediately assigned a unique identifier and is remotely scanned for vital signs, and a full image scan is taken.

At least a portion of the image is compared to various parameters and databases for signs of trauma, evaluation of appearance (skin, hair, nails, etc.), movement and cognition. At least a portion of the image is optionally compared with medical history by way of facial recognition. In such a case, a subject then enters the queue based on its Characteristic Values reflected by the Criticality Value which generates the Queue Status Indicator.

Once the subject has been placed in the queue, additional scans are initiated, including EEG for possible schizophrenia or determination of level of consciousness. For example, a dedicated camera or other dedicated equipment is used for sensing level of consciousness or alertness.

In one embodiment, the system includes at least one computing processor that utilizes at least one set of instructions derived from mathematical trends such as queuing theory. For example, the theory of mathematical queuing allows for derivation and calculation of several performance measures including the average wait time in the queue or the system, the expected number waiting or receiving service, and probability of encountering the system in various states (e.g., empty, full, having an available server or having to wait a certain amount of time to be served).

As shown in FIG. 2, in one embodiment describing methods, systems, and computer program products described herein, one or more subjects are assessed in a healthcare facility, depending on each subject's health condition. The data from each of the subjects is collected and compared with all other subjects awaiting medical treatment. Each subject is assigned a Queue Status Indicator based on the Criticality Value of each subject compared with the rest of the subjects awaiting treatment, and in one embodiment, an optional indicator locates the most critical subject waiting treatment.

In one embodiment, at least one dataset described herein includes a dynamic data structure. In one embodiment, at least one dataset described herein includes a static data structure. In one embodiment, a subject is assessed based on queries of a Characteristic Value dataset. In one embodiment, the Characteristic Value query includes at least one of a DCQ, observed or sensed characteristic, or input based on the subject's health history or health records. In one embodiment, the Characteristic Value query includes a survey from an input/output device, for example. In one embodiment, the survey can be in any language, or in pictorial or other form. In one embodiment, the survey includes skip logic, or conditional branching, that allows for the survey to be customized for the subject based on the subject's previous responses. For example, if a subject's first query includes asking whether the subject is male or female, and the subject answers “female,” then the survey skip logic rules could be such that it forces the subject to skip questions related to exclusively male symptoms or conditions.

In one embodiment, a particular Characteristic Value is coupled to the Criticality Value more tightly than another particular Characteristic Value. For example, a heavier weight might be given to a tightly coupled Characteristic Value (e.g., heart rate, respiration, etc.). In one embodiment, one or more Characteristic Values are weighted heavier, thus generating a higher Criticality Value when included in the subject's response, and elevating the subject in the queue. For example, a heavier weight can be given to a characteristic that is sensed or present in the subject's health records, and a lesser weight to a self-reported characteristic, particularly when the data collected appears to be contradictory or inconsistent.

As shown in FIG. 3, the dynamic dataset described as part of one embodiment of the systems, methods, and computer program products described herein, a first subject is assessed and enters the queue. The Queue Status Indicator of each subject indicates the sequential order in which subjects will receive medical attention. As described, the Queue Status Indicator numerical value is based on the Criticality Value dataset, which in turn is based on the assessment of one or more characteristics of each subject. In one embodiment, if a subject's Criticality Value is above a threshold that requires continuous or intermittent monitoring, and the subject's Criticality Value increases, the QSI dataset is updated, and the subject immediately receives a higher Queue Status Indicator.

As indicated by the asterisk (*) in FIG. 3, a subject who has a sudden increase in Criticality Value has a corresponding increase in his or her Queue Status Indicator and advances in the queue. In the case where the subject's Queue Status Indicator changes dramatically, the subject may be eligible for immediate treatment or next in line medical treatment.

In one embodiment, when a subject has been assessed and assigned a QSI, and the subject's Criticality Value decreases, the updated Criticality Value dataset and updated QSI dataset re-assign a QSI based on the decreased Criticality Value, which may place the subject in a lower or later sequential order compared with the other subjects in the queue. Likewise, when a subject receives medical attention, his or her Criticality Value(s) and QSI are removed from the respective datasets, updating optionally in real time.

As shown in FIG. 4, the system 102 includes a computing device 112 with optionally one or more of a receiver 106, transceiver 108, transmitter 110, memory 116, or power source 115. In one embodiment, as described, the dynamic dataset includes a compilation of data from each assessed subject in the queue. For example, Subject #1 is assessed, generating XYZ data (one or more Characteristic Values based on one or more assessed characteristics of the subject), which provide the basis for generation of a Criticality Value for Subject #1 based on the Criticality Value dataset, the XYZ data enters the Criticality Value dataset. Since the Criticality Value dataset was previously empty (or had zero value), the subject is assigned a Queue Status Indicator (in this case #1) accordingly.

Next, Subject #2 is assessed, generating ABC data (one or more Characteristic Values based on one or more assessed characteristics of the subject), which provides the basis for generation of a Criticality Value for the subject based on comparison with the Criticality Value dataset, as ABC data enters the Criticality Value dataset. The data from Subject #2 is compared with the other data in the Criticality Value dataset and the subject is assigned a Queue Status Indicator accordingly.

Finally, Subject #3 is assessed, generating VQF data (one or more Characteristic Values based on one or more assessed characteristics of the subject), which provides the basis for generation of a Criticality Value for the subject based on comparison with the Criticality Value dataset, as VQF data enters the Criticality Value dataset. The data from Subject #3 is compared with the other data in the Criticality Value dataset and the subject is assigned a Queue Status Indicator according to where the subject's Criticality Value ranks with the other subjects' Criticality Values in the dataset.

Addition to the dataset of any number of data from assessed subjects in the queue can cause a shift in the previously assigned Queue Status Indicator of any subject, depending on the Queue Status Indicator assigned to the added subject(s). Likewise, at the time a subject receives medical attention, his or her QSI and Criticality Value data are removed from the respective datasets. Such removal of data can result in a shift in the remaining subjects' Criticality Value(s) and QSI, in response to the dynamic dataset changes.

FIG. 5 illustrates one embodiment that includes a system 155 including at least one computing device 100. The computing device can take various forms or be part of an object, such as a limited resource computing device, a wireless communication device, a mobile wireless communication device, an electronic pen, a handheld electronic writing device, a digital camera, a scanner, an ultrasound device, an x-ray machine, a non-invasive imaging device, a cell phone, a PDA, an electronic tablet device, a medical apparatus (implantable or otherwise), a printer, a car, and an airplane.

The computing device 100 is operably connected to at least one input/output device (see other Figures) for which the subject 104 can interact. For example, in an embodiment, the system 155 includes an accepting unit 119, which interacts with a user 118 (can be self-reported information, sensed information, or information obtained from health history records or family members, etc. given to a health care worker) that causes the input 111. In addition, if one or more sensors are employed, information is sensed 113. The system 155 further includes a comparator for the Characteristic Value dataset 114, which is operably coupled to electronic health records or family health history 115. In an embodiment, the system 155 further includes at least one Generating Unit 117 for one or more Characteristic Values for the subject. In an embodiment, the system 155 includes a Comparator 123 for the Criticality Value Dataset and a Generating Unit for Criticality Value(s) 119. In an embodiment, the system 155 includes an Assigning Queue Indicator Status Unit 125, and output 129.

FIG. 6 indicates an embodiment in which Subject #1 provides a response that generates a Characteristic Value dataset (can be static or dynamic), based on one or more queries, for example. From the Characteristic Value dataset, the Subject #1's Criticality Value Based on Characteristic Values and optionally health history/records are determined. As shown, if one or more of a subject's Characteristic Values exceeds a [predetermined] threshold, one or more of the subject's Characteristic Values are monitored as additional queries, or the subject's Criticality Value is automatically elevated above the highest Criticality Value in the dataset, causing the subject to receive the highest Queue Status Indicator of all assessed subjects awaiting medical attention.

Next, if a subject's Criticality Value exceeds a [predetermined] threshold, one or more Characteristic Values monitored for change, or the subject's Criticality Value is automatically elevated above the highest Criticality Value in the dataset, causing the subject to receive the highest queue status indicator of all assessed subjects awaiting medical attention. In an embodiment, once the subject's Criticality Value has been determined, the Criticality Value is compared with the Criticality Value dataset based on Criticality Values of all assessed subjects awaiting medical attention. Next, the Queue Status Indicator of each subject with a Criticality Value in the Criticality Value dataset is determined. Then a subject receives medical attention and its Critical Value is removed from the Criticality Value dataset.

In certain instances, one or more components of the computing device 720 may be deemed not necessary and omitted. In other instances, one or more other components may be deemed necessary and added to the computing device.

In certain instances, the computing system typically includes a variety of computer-readable media products. Computer-readable media may include any media that can be accessed by the computing device 720 and include both volatile and nonvolatile media, removable and non-removable media. By way of example, and not of limitation, computer-readable media may include computer storage media. By way of further example, and not of limitation, computer-readable media may include a communication media.

Computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules, or other data.

Communication media may typically embody computer-readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism and include any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media include wired media, such as a wired network and a direct-wired connection, and wireless media such as acoustic, RF, optical, and infrared media.

The computing device 720 may also include other removable/non-removable, volatile/nonvolatile computer storage media products.

The network may include a LAN network environment, or a WAN network environment, such as the Internet. In a networked environment, program modules depicted relative to the computing device 720, or portions thereof, may be stored in a remote memory storage device.

All of the above U.S. patents, U.S. patent application publications, U.S. patent applications, foreign patents, foreign patent applications and non-patent publications referred to in this specification and/or listed in any Application Data Sheet, are incorporated herein by reference, to the extent not inconsistent herewith. Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware, software, and/or firmware implementations of aspects of systems; the use of hardware, software, and/or firmware is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.

In some implementations described herein, logic and similar implementations may include software or other control structures suitable to operation. Electronic circuitry, for example, may manifest one or more paths of electrical current constructed and arranged to implement various logic functions as described herein. In some implementations, one or more media are configured to bear a device-detectable implementation if such media hold or transmit a special-purpose device instruction set operable to perform as described herein. In some variants, for example, this may manifest as an update or other modification of existing software or firmware, or of gate arrays or other programmable hardware, such as by performing a reception of or a transmission of one or more instructions in relation to one or more operations described herein. Alternatively or additionally, in some variants, an implementation may include special-purpose hardware, software, firmware components, and/or general-purpose components executing or otherwise invoking special-purpose components.

Alternatively or additionally, implementations may include executing a special-purpose instruction sequence or otherwise invoking circuitry for enabling, triggering, coordinating, requesting, or otherwise causing one or more occurrences of any functional operations described above. In some variants, operational or other logical descriptions herein may be expressed directly as source code and compiled or otherwise invoked as an executable instruction sequence. In some contexts, for example, C++ or other code sequences can be compiled directly or otherwise implemented in high-level descriptor languages (e.g., a logic-synthesizable language, a hardware description language, a hardware design simulation, and/or other such similar mode(s) of expression). Alternatively or additionally, some or all of the logical expression may be manifested as a Verilog-type hardware description or other circuitry model before physical implementation in hardware, especially for basic operations or timing-critical applications.

In certain cases, use of a system or method may occur in a territory even if components are located outside the territory. For example, in a distributed computing context, use of a distributed computing system may occur in a territory even though parts of the system may be located outside of the territory (e.g., relay, server, processor, signal-bearing medium, transmitting computer, receiving computer, etc. located outside the territory). A sale of a system or method may likewise occur in a territory even if components of the system or method are located and/or used outside the territory.

Further, implementation of at least part of a system for performing a method in one territory does not preclude use of the system in another territory.

One skilled in the art will recognize that the herein described components (e.g., operations), devices, objects, and the discussion accompanying them are used as examples for the sake of conceptual clarity and that various configuration modifications are contemplated. Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar is intended to be representative of its class, and the non-inclusion of specific components (e.g., operations), devices, and objects should not be taken limiting.

Those skilled in the art will appreciate that a user may be representative of a human user, a robotic user (e.g., computational entity), and/or substantially any combination thereof (e.g., a user may be assisted by one or more robotic agents) unless context dictates otherwise.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations are not expressly set forth herein for sake of clarity.

The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures may be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “operably coupled to” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components, and/or wirelessly interactable, and/or wirelessly interacting components, and/or logically interacting, and/or logically interactable components.

In some instances, one or more components may be referred to herein as “configured to,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that “configured to” can generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise.

While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”

With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flows are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.

Various non-limiting embodiments are described herein as Prophetic Examples.

Prophetic Example 1 Automatic Patient Data Collection System for Emergency Department Waiting Room

An automatic data collection system is constructed in an emergency department waiting room and used to prioritize the patients for receiving medical attention by ranking each subject with a Queue Status Indicator (QSI). A prospective patient is registered upon entering the waiting room by interaction with a touch screen computer (e.g., iPad2 from Apple, Inc., Cupertino, Calif.) and a fingerprint sensor (e.g., Lumidigm Venus fingerprint sensor from Lumidigm Inc., Albuquerque, N. Mex.; see Lumidigm Venus Datasheet which is incorporated herein by reference). The computer is programmed to interact verbally and by touch with the patient. The patient is prompted to touch the fingerprint sensor and the fingerprint data is compared to a database (which may be site wide [health care center, hospital, etc.], citywide, statewide or nationwide) of patient medical records. If no matching medical record is found, the computer queries the patient by voice and “on-the-screen” to obtain registration information and to create a new medical record for the patient that includes the fingerprint data. Any verbal information provided by the patient is displayed on the computer screen and confirmed by touching the screen. The touch screen computer also has a camera to record the height of the patient and a facial photograph, which are also transmitted to a central computer and recorded in the medical record. If the patient has a pre-existing medical record, the patient may be queried by the computer to update the medical record. For example, the patient's current address, phone number and insurance coverage may be verified. The computer also asks the patient to choose between automated physiologic data collection and non-automated data collection. If the patient chooses automated data collection then a designated chair in the waiting room is activated, and the patient is directed to sit in the chair designated by a flashing light.

The designated chair in the waiting room contains interacting sensors to verify the patient's identity and to measure and record physiological parameters of the patient. When the patient sits down, the patient is prompted by a flashing light to touch a fingerprint sensor on the chair (sensor may be directly touching the subject). Once the patient touches the screen or otherwise engages the system, the available space flashing light indicator stops. Recognition of the patient's fingerprint by a central computer results in successive activation of sensors to determine the patient's weight, electrocardiogram, heart rate, respiration rate, temperature, and blood oxygen level. The patient's weight is determined by an electronic scale under the chair, which automatically transmits the weight and date to a central computer containing the patient's medical record(s). The patient's electrocardiogram is determined by electric potential sensors, which may be placed 1 meter apart on opposite sides of the chair (not directly touching the subject). Nonconductive electric potential sensors to determine a patient's electrocardiogram are described (see e.g., Harland et al., Meas. Sci. Technol. 13, 163-169, 2002, which is incorporated herein by reference). The patient's respiration rate and heart rate may be determined by a remote sensor that detects physiological activities by illuminating the patient with radio frequency (RF) electromagnetic signals and detecting the reflected electromagnetic signal waves. The sensor may be incorporated in the back of the chair. A remote sensor to detect respiration and heart rate is described (see e.g., U.S. Pat. No. 7,272,431, which is incorporated herein by reference). The patient's body temperature is determined by thermal imaging with a radiometric camera (e.g., a 7320 ETIP camera available from Infrared Cameras, Inc., Beaumont, Tex.; see Spec. Sheet IR camera, which is incorporated herein by reference). The infrared camera is installed in the wall in front of the patient's chair and focused on the patient's forehead or eyes. Devices and methods to determine core body temperature noninvasively and remotely are described (see e.g., U.S. Pat. No. 7,340,293, which is incorporated herein by reference).

The patient's hematocrit and blood oxygen concentration are determined by a photoplethysmograph device on the armrest of the chair. A system with a finger clip emits and detects different wavelengths of light through the tissue of the finger (see e.g., Shaltis, et al., Conf. Proc. IEEE Eng. Med. Biol. Soc. 4: 3567-3570, 2005, which is incorporated herein by reference). The extinction of selected wavelengths of light is detected and may be used to determine the hematocrit and the blood oxygen saturation value. For example, a system and method to measure hematocrit and blood oxygenation by transilluminating the patient's finger with light at wavelengths of 660 nm, 805 nm and 1550 nm is described (see e.g., U.S. Pat. No. 5,372,136, which is incorporated herein by reference). The biometric and physiological parameters determined remotely by the automatic data collection system in the waiting room are transmitted wirelessly to a central computer that communicates with health information databases (e.g., Kaiser Permanente electronic health records may be accessed using EpicCare software from Epic Systems Corp, Verona, Wis.; and Centers for Disease Control, Data and Statistics are available online at: cdc.gov/datastatistics, the subject matter of which is incorporated herein by reference). Wireless sensor networks for aggregating and transmitting physiological data to a central computer are described (see e.g., Gao et al., Proc. IEEE Conf. Technologies for Homeland Security, pp. 187-192, 2008, which is included herein by reference).

The automatic data collection system includes computer programs and methods to compare the patient's physiological parameters to parameters obtained, for example, from healthy individuals, to the patient's medical history, and most importantly, to the dataset obtained from each prospective patient that enters the emergency department waiting room. The system includes a central computer with programs to compare datasets from the emergency room patients and prioritize the patients for medical attention. Computer programs to evaluate and compare physiological datasets are described (see e.g., the paper titled: OSCAR-MDA An Artificially Intelligent Advisor for Emergency Room Medicine by John L. Pollock and Devin Hosea printed on Oct. 18, 2011 and available online at citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.49.4970&rep=rep&type=pdf and Pollock, Cognitive Carpentry: A Blueprint for How to Build a Person, MIT Press, Cambridge, Mass., 1995, each of which is incorporated herein by reference.) Once a patient is assessed, and his or her Characteristic Value(s) are generated based on the assessed characteristics, a Criticality Value is generated by comparison with the Criticality Values of the other patients already in the queue. From this comparison, a Queue Status Indicator is assigned to the patient, ranking him among others in the queue awaiting medical attention. A list of the prioritized patients, their location (e.g., designated waiting room chair), and their biometric and physiological data are transmitted to triage nurses in the Emergency Room who attend to the patients in the order indicated by the Queue Status Indicator.

The identity of the patients is verified by repeating the fingerprint scan using the fingerprint sensor and comparing the fingerprint data to a database containing electronic medical records. The designated chair occupied by the patient is converted to unoccupied status once the triage nurse verifies the patient's identity and attends to the patient.

Prophetic Example 2 Automatic Patient Data Collection System for Hospital Healthcare Workers

A nurse who cares for patients receiving hematopoietic stem cell transplants is screened by an automatic data collection system for evidence of infectious disease or the presence of a pathogen before gaining access to the hospital. Such a determination can be based at least in part, on the subject's own health history or on standardized values. A hospital pre-entry room contains remote sensors which are wirelessly connected to a central computer that is programmed to compile and analyze the biometric and physiological data obtained from the nurse. The nurse is identified by iris scanning with a wall-mounted iris scanner (e.g., an Iris Scanner System is available from Bayometric, Inc., San Jose, Calif.; see Biometric Iris Access Specif. Sheet which is incorporated herein by reference). The iris scanner system transmits iris images and face images to a central computer that compares the images to stored data to authenticate the nurse's identity. After authentication, the central computer activates a video camera and remote sensors to detect signs of infectious disease in the nurse.

A video is recorded while the nurse is screened by remote sensors. First, an electronic nose is activated to sample the employee's breath and detect chemicals indicative of microbial infection. For example, an electronic sensor array may detect gases indicative of a respiratory infection by pathogens, such as influenza virus, rhinovirus, adenovirus, Streptococcus, Staphylococcus, and Mycobacterium tuberculosis. Methods and devices to detect chemicals given off by microbial pathogens are described (see e.g., U.S. Patent Application No. 2004/0006257, which is incorporated herein by reference). Electronic nose sensor array response profiles may be used to distinguish healthy and diseased individuals or carriers and non-carriers of a pathogen. Also a database of response profiles corresponding to healthy and infected individuals or carriers and non-carriers of a pathogen may be stored on the central computer and used for comparison to the nurse's current response profile. Stored electronic nose response profiles may include profiles unique to many different bacterial, viral and fungal pathogens. Results from the electronic nose screening are compiled in the central computer for analysis and a remote sensor is activated to measure body temperature. The nurse's body temperature is determined by thermal imaging with a radiometric camera (e.g., a 7320 ETIP camera available from Infrared Cameras, Inc., Beaumont, Tex.; see Spec. Sheet IR Camera, which is incorporated herein by reference). The infrared camera is installed in the wall in the pre-entry room and is focused on the nurse's forehead or eyes. Devices and methods to determine core body temperature noninvasively and remotely are described (see e.g., U.S. Pat. No. 7,340,293, which is incorporated herein by reference). The body temperature is wirelessly transmitted to a central computer and compared to the nurse's mean body temperature for the previous month. Moreover the nurse's physiologic data including the electronic nose response profile, the body temperature and the video data are analyzed by the central computer using dedicated software to determine if the nurse displays signs of infection. Computer programs to evaluate and compare physiological datasets are described (see e.g., the paper titled: OSCAR-MDA An Artificially Intelligent Advisor for Emergency Room Medicine by John L. Pollock and Devin Hosea printed on Oct. 18, 2011 and available online at citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.49.4970&rep=rep1&type=pdf and Pollock, Cognitive Carpentry: A Blueprint for How to Build a Person, MIT Press, Cambridge, Mass., 1995, which are incorporated herein by reference).

If video analysis or any other sensors (i.e., electronic nose and IR camera) indicate an infection may be present, the nurse may be denied access to the hospital until he or she talks with their immediate supervisor or a health safety officer for clearance. If an infection is suspected, the nurse may be required to submit an oral or nasal sample for analysis of microbial pathogens. The sample may be analyzed on a microfluidic chip located in the pre-entry room that utilizes biochemical assays for nucleic acids derived from microbial pathogens. For example, a microfluidic chip designed to detect viral and bacterial pathogens using polymerase chain reaction is described (see e.g., Chen et al, Ann. N.Y. Acad. Sci. 1098: 429-436, 2007, which is incorporated herein by reference). Data on detection of viral or bacterial pathogens (e.g., influenza virus, rhinovirus, adenovirus, Streptococcus pneumoniae, Staphylococcus aureus, and/or Mycobacterium tuberculosis) are automatically transmitted to a central computer by the system, and the nurse, the supervisor, or a health safety officer is notified. If a pathogenic infection is detected, the nurse will be sent home for the day or heightened precautions may be taken, such as the nurse wearing a face mask and avoiding unnecessary contact with patients.

Prophetic Example 3 Automatic Patient Data Collection System for The Waiting Room of A Primary Care Clinic

An adult patient makes an appointment to see a primary care physician due to chest pressure. The patient interacts with an automatic data collection system upon arrival at the doctor's office. The automatic data collection system includes a touch screen computer with a video camera; remote, nonconductive physiological sensors; a central computer and programming to collect and compare a patient's physiological data to electronic health records; and health information database(s).

Upon entering the waiting room, the patient can check in with a receptionist or with a touch screen computer installed adjacent to the reception desk. The patient is registered by interaction with a touch screen computer (e.g., iPad 2 from Apple, Inc., Cupertino, Calif.) and a fingerprint sensor (e.g., Lumidigm Venus fingerprint sensor from Lumidigm Inc., Albuquerque, N. Mex.; see Lumidigm Venus Datasheet which is incorporated herein by reference). The touch screen computer is programmed to interact verbally and by touch with the patient, so that any verbal information provided by the patient is displayed on the computer screen and confirmed by touching the screen. The patient is prompted to touch the fingerprint sensor, and the patient's name and fingerprint data are transmitted to a central computer, and compared to a database (which may be site wide, citywide, statewide or nationwide) of patient medical records. If no matching medical record is found, the touch screen computer queries the patient by voice and “on-the-screen” to obtain essential information including name, address, birth date, health insurance information, credit card number, and the reason for the visit. The patient information is sent to the central computer and added to an existing health record, or is used to create a new medical record for the patient that includes the fingerprint data. The touch screen computer also has a camera to record the height of the patient and a facial photograph, which are also transmitted to the central computer and recorded in the medical record(s). If the patient has a pre-existing medical record the patient may be queried by the touch screen computer to update the medical record. For example, the patient's current address, phone number, and insurance coverage may be verified by interacting verbally or by touching the computer keyboard or screen.

The patient is asked to choose between automatic physiologic data collection by remote, nonconductive sensors, or by manual data collection by a healthcare worker at the time of the appointment. If the patient chooses automated data collection, then a designated chair in the waiting room is activated, and the patient is directed to sit in the chair designated by a flashing light. When the patient sits in the designated chair, the flashing light stops, and an electronic scale in the floor measures the patient's weight and sends it to the central computer, which calculates the body mass index (BMI) of the patient and finds the patient is overweight with a BMI equal to 35. Based on the patient's weight and complaint of chest pressure, the system activates remote sensors to measure heart function.

First, a remote, nonconductive sensor is activated to measure the patient's respiration rate and heart rate. A remote sensor illuminates the patient with radio frequency (RF) electromagnetic signals and detects the reflected electromagnetic signal waves. The RF sensor may be incorporated in the back of the chair. A remote sensor to detect respiration and heart rate is described (see e.g., U.S. Pat. No. 7,272,431, which is incorporated herein by reference). Data on the heart rate and respiration rate of the patient are transmitted to a central computer and compared to the patient's previous data on heart rate and respiration rate, as well as normal healthy values for these physiological parameters. The computer determines that the patient's heart rate is abnormal and sends an email message to the physician indicating an abnormal heartbeat is occurring. The central computer also activates a remote nonconductive sensor to determine the patient's electrocardiogram. Ultra-high-input—impedance electric potential sensors in each armrest of the chair adjacent to the patient's arms or torso obtain a single, or together a differential, measurement of the electrical potential signals of the heart. Nonconductive electric potential sensors to determine a patient's electrocardiogram (ECG) are described (see e.g., Harland et al., Meas. Sci. Technol. 13, 163-169, 2002, which is incorporated herein by reference). For example, a first order, differential, high resolution ECG is recorded using two electric potential probes, and is transmitted to a central computer where it is compared to previous ECGs for the patient and to ECGs from normal, healthy individuals. The shape and time intervals for the P wave, QRS complex and T wave are evaluated. Computer analysis of the patient's electrocardiogram verifies the abnormal heartbeat detected with the RF sensor and sends another email to the physician highlighting the abnormal ECG aspects and recommending additional evaluation of heart function, such as a 12-electrode ECG and blood biochemistry assays that may provide indications of heart dysfunction. For example, the computer may recommend determining blood electrolytes (e.g., sodium and potassium), measures of renal function, measures of liver function, a complete blood count and measures of blood concentrations of troponin and B-type natriuretic peptide.

Next, the patient's hematocrit and blood oxygen concentration is determined by a photoplethysmograph device on the armrest of the chair. A system with a finger clip emits and detects different wavelengths of light through the tissue of the finger (see e.g., Shaltis, et al., Conf. Proc. IEEE Eng. Med. Biol. Soc. 4: 3567-3570, 2005, which is incorporated herein by reference). The extinction of selected wavelengths of light is detected and may be used to determine the hematocrit and the blood oxygen saturation value. For example, a system and method to measure hematocrit and blood oxygenation by transilluminating the patient's finger with light at wavelengths of 660 nm, 805 nm and 1550 nm is described (see e.g., U.S. Pat. No. 5,372,136, which is incorporated herein by reference).

The central computer next activates an infrared camera to measure the patient's temperature. The patient's body temperature is determined by thermal imaging with a radiometric camera (e.g., a 7320 ETIP camera available from Infrared Cameras, Inc., Beaumont, Tex.; see Spec. Sheet IR camera which is incorporated herein by reference). The infrared camera is installed in the wall in front of the patient's chair and focuses on the patient's forehead or eyes. Devices and methods to determine core body temperature in a noninvasive and remote manner are described (see e.g., U.S. Pat. No. 7,340,293, which is incorporated herein by reference). The patient's temperature is transmitted to the central computer and added to their medical record.

The physiological parameters determined remotely by the automatic data collection system in the waiting room are transmitted wirelessly to a central computer that communicates with health information databases (e.g., Kaiser Permanente electronic health records may be accessed using EpicCare software from Epic Systems Corp, Verona, Wis.; Centers for Disease Control, Data and Statistics are available online at cdc.gov/datastatistics, the subject matter of which is incorporated herein by reference). Wireless sensor networks for aggregating and transmitting physiological data to a central computer are described (see e.g., Gao et al., Proc. IEEE Conf. Technologies for Homeland Security, pp. 187-192, 2008, which is incorporated herein by reference).

The automatic data collection system includes computer programs and methods to compare the patient's physiological parameters to parameters obtained from healthy individuals, and to the patient's medical history. The system includes a central computer with programs to compare multiple datasets, identify acute care situations and alert and advise healthcare workers. Computer programs to evaluate and compare physiological datasets are described (see e.g., OSCAR-MDA An Artificially Intelligent Advisor for Emergency Room Medicine, OSCAR-DSS, OSCAR Project Technical Report, 1997, by John L. Pollock and Devin Hosea printed on Oct. 18, 2011 and available online at citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.49.4970&rep=rep1&type=pdf, and Pollock, Cognitive Carpentry: A Blueprint for How to Build a Person, MIT Press, Cambridge, Mass., 1995, which are incorporated herein by reference). An updated medical record including the current physiological parameters is provided to the health care giver (e.g., primary care physician) prior to seeing the patient. Moreover, acute medical situations are indicated by alerts issued by the system, based on the assessed characteristics of the patient in comparison with the Criticality Value dataset.
